## Indications for use
The Stackable Cage” System is indicated for use in the thoracolumbar spine (i.e., T1 to LS) to replace a diseased vertebral body resected or excised for the treatment of tumors, to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. The Stackable Cage System is designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column even in the absence of fusion for a prolonged period. The Stackable Cage system is intended for use with supplemental internal fixation. The supplemental internal fixation systems that may be used with the Stackable Cage System include DePuy AcroMed titanium plate or rod systems (e.g., Kaneda SR, University Plate, M-2, ISOLA, VSP, Moss Miami, TiMX, and Profile).
